ไทยOn the morning of May 20, 2025, Chulalongkorn University’s Faculty of Engineering, in collaboration with The University of Tokyo, held the first Joint Coordination Committee (JCC) meeting for the research project “Data-Driven Dynamic Transport Management in Emerging Metropolis for Climate Change Mitigation” which is nicknamed as “3DTraffic.” The principal investigators of the research project are Professor Daisuke Fukuda from the University of Tokyo and Professor Kasem Choocharukul from Chulalongkorn University.
.
The meeting held in a hybrid fashion in Meeting Room 1106 on the 11th floor of the Centennial Memorial Building, Faculty of Engineering, Chulalongkorn University. Associate Professor Dr. Witaya Wannasuphoprasit, Dean of the Faculty of Engineering of Chulalongkorn University, chaired the meeting. Participants included representatives from various Thai government agencies involved in transportation planning and traffic management in Bangkok, representatives from Japanese government agencies, and researchers from various institutions who are the members of the 3DTraffic project.
.
The JCC meeting was organized to lay a mutual understanding of the overall project plans, structure, goals, and details of the research plan for the 3DTraffic project. This project operates under the Science and Technology Research Partnership for Sustainable Development (SATREPS) program, a joint initiative of the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). One of the key objectives of this meeting was to request cooperation, particularly in sharing traffic data for research purposes. The project received an overwhelmingly positive response from the representatives of the participating Thai government agencies. These included the Bangkok Metropolitan Administration’s Traffic and Transportation Department (TTD), the Office of Transport and Traffic Policy and Planning (OTP), the Department of Highways (DOH), the Expressway Authority of Thailand (EXAT), the Department of Land Transport (DLT), the Department of Rural Roads (DRR), the Department of Public Works and Town & Country Planning (DPT), the Royal Thai Police (RTP), and the Thailand International Cooperation Agency (TICA). Furthermore, the project welcomed representatives from Japanese government agencies, including the Embassy of Japan in Thailand, JICA, and JST.
.
At the end of the meeting, Mr. Shunsuke Kawahara, Senior Advisor for Transportation Infrastructure from JICA, delivered closing remarks. He emphasized the significance of this project, stating that the collaboration between the research team and various agencies under the 3DTraffic project will lead to stronger ties between Japan and Thailand that will further promote sustainable development for Thailand.
Continuing on the same day, the 3DTraffic project organized the Project Kick-off Symposium in the Meeting Room on the 2nd floor of Engineering Building 4, Faculty of Engineering, Chulalongkorn University. This seminar was conducted to disseminate a detailed understanding of the project’s research plan, and it was open to representatives from the agencies who attended the JCC meeting in the morning and representatives from other organizations in the public, private, and academic sectors. There were approximately 90 participants both onsite and online. The symposium featured an interactive panel discussion session in which audience engagement was successfully fostered, allowing attendees to contribute feedback about roles of 3DTraffic in real-time.
.
Professor Kasem Choocharukul, the Co-Principal Investigator, delivered the opening remarks and expressed his confidence that the project, where experts and researchers from various sectors gather to make joint efforts, will be able to foster three “good things” as per the project’s nickname “Sam Dee Traffic” (three good things about road traffic): faster, greener, and safer traffic. Furthermore, Professor Daisuke Fukuda, the Principal Investigator, gave an overview to introduce the project, enabling attendees to understand its background and objectives.
The project was highly honored to welcome Mr. Haruka Ozawa, First Secretary from the Embassy of Japan in Thailand, who delivered a speech on the cooperation between Japan and Thailand in developing transportation infrastructure, which is crucial for urban and national development. Further, the project was honored to have Distinguished Professor Yoshitsugu Hayashi from Tokaigakuen University deliver a keynote lecture related to his previous SATREPS project in Bangkok.
.
The 3DTraffic project has 4 working groups for research on various topics related to traffic management, ranging from traffic-data analysis and modeling techniques to traffic management methods and traffic signal control. One of the main goals of this project is to develop a prototype Digital Twin model, which will serve as an important data foundation for developing effective traffic management models and methods in real-world areas. In this symposium, all 4 working groups presented their background and research plans. The research topic and the representatives of each Working Group are as follows:
● Working Group 1: Advanced Traffic Condition Estimation Methodology Using Data Fusion Techniques, led by Assoc. Prof. Toru Seo and Asst. Prof. Garavig Tanaksaranond
● Working Group 2: Evaluation of Travel Demand Management Measures Using an Activity-based Microsimulation, led by Prof. Daisuke Fukuda and Assoc. Prof. Veera Muangsin
● Working Group 3: Macroscopic Analysis of the Dynamic Traffic State on a City Scale, led by Assoc. Prof. Kentaro Wada and Assoc. Prof. Chaodit Aswakul
● Working Group 4: Proposal and Application of an Intersection-level Microscopic Traffic Signal Control, led by Prof. Takashi Oguchi and Assoc. Prof. Sorawit Narupiti (presenter: Dr. Somporn Sahachaiseree)
